I've been watching videos of human & animal robots for years. With all due respect to Big Dog and other robots navigating obstacles and remaining upright after a collision on ice, are walking robots really superior to tracked robots? Tracks/treads are potentially much faster and I've seen designs navigate all sorts of obstacles (even climb) just as fast or faster than walking robots.

I see this work evolving into prosthetics and bionics, rather than delivering supplies in the battlefield.

And Atlas looks like Hector from SATURN 3. Now there was a creepy robot.

Rather than build these robots they should grow animals in vats that are brainless and then place a computer in the empty brain cavity wired up to the body and control it via a human on a computer or give it advanced AI.

orrrrrrrrrrrrrrrrrrrrr not. That would be something from a horror movie.

I actualy like these four legged robots, there is great potential to this kind of technology.

The usefulness of this robot is that it can go where human legs can...far more places than wheels. The only thing that might be more useful is a drone that hovers...but it would probably take to much power to keep steady and aloft with supplies. The one big problem with BigDog...it's incredibly, painfully, dangerously loud!
